Electropolishing removes material while electroplating adds material. Electropolishing and electroplating have similar setups, but they involve opposite reactions. Both are electrochemical reactions, however, in electropolishing the work-piece is charged anodically (thus loses ions) and in electroplating the work-piece is charged cathodically (gains ions).
